Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722470, here are decompositions:

11 + 8722459 = 8722470
23 + 8722447 = 8722470
41 + 8722429 = 8722470
47 + 8722423 = 8722470
61 + 8722409 = 8722470
79 + 8722391 = 8722470
103 + 8722367 = 8722470
109 + 8722361 = 8722470

Showing the first eight; more decompositions exist.
